DIY Sankor 16C clamp

Oliver Sutton

Recommended Posts

Hi guys this is my first post and i'm gonna share a DIY clamp i did.

I've read somewhere that a Helios 44M is the perfect companion for the Sankor 16C , so i bought that,

After blowing my budget i was left with not much for a clamp.

At first i used a step-down adapter which ended up looking pretty bad:










It did the job though, for a while :D

After being concerned about the safety of that rig i decided to get to work.

For that used a 52mm extension tube that i found on eBay for $13:


Tools needed are a drill, a tap set (looks like a screw to create thread in holes), 3 screws or bolts or hex screw, and some oil (to use the tap set, it has to go smooth). I ended up using M5 hex screws (metric 5mm).

Unfortunatly i didn't document the procedure but it's very easy, there's plenty of guides on google.

Clamp version 2.0 looked more promising:












Looks pretty similar to the clamp from Vid-Atlantic, doesn't it ?


As you can see on those pics, my Sankor has no thread. Well, i filed it as much as possible without breaking it.

I didn't do that randomly, i wanted the lens as snug as possible to the clamp.

It also allowed me to sit the Sankor very close to the glass of the Helios by simply removing the front ring (of the Helios):






And the result is a very tight and snug unit that actually look like one single lens:








I already had all the tools needed so cost of production ended up being $13 (tube) + $2 (hex screws)

If you guys can use your hands and a drill, you can do it too.

Back side of it when i measure across 3 7/8 i was thinking of doing what you did but i am going to need some tap set. You said that you took off Helios front so it comes closer to the sankor which i have does this eliminate some of the vignetting?


I was thinking of using plastic tube between my anamorphic lens and taking lens know that my lens cant be supported by taking lens since its 5 lbs i will mount it on a rail system.

      Hi, I am selling a Kowa 16-D anamorphic lens in excellent condition. It's an amazing piece of gear if you're into anamorphic shooting. It is very sharp, it produces wonderful subtle blue/purple flares (I usually dislike flares but I'm in love with these) and it has great anamorphic character. It is also very lightweight.

      The Kowa 16-D is in great condition. I bought it on Ebay this summer but I have barely used it and it has been stored very safely in a dry box. The glass is in pristine condition and the image quality is superb. Some signs of wear on the rear barrel but totally insignificant, especially since this part will be hidden behind your clamp. Comes with Kowa front and rear caps.

      I am selling it with a Redstan clamp with 52mm thread made specifically for this lens. Redstan clamps are known as the highest-quality clamps on the market for vintage anamorphic lenses. If needed, I can also include a 55 to 52mm step-down ring as a gift (if your taking lens has a 55mm filter thread).

      Finally, I am also selling an HTN adapter ring that can be screwed onto the Kowa 16-D to attach the Rectilux Hardcore DNA. Though never used, this is an incredibly useful piece of gear if you want to turn this set-up into a stable single-focus solution.

      Price: $370 for Kowa 16-D and Redstan Clamp
      +$35 for HTN Adapter ring (buyer pays for shipping)

      Please let me know if you want to see any video samples and I can PM you some files. Please also understand that this lens is smaller than the Kowa 16-H or Bell & Howell and could cause some vignetting depending on your taking lens and camera sensor. If you have any questions, do not hestitate to ask! Cheers.

      Let me introduce Angle HDMI Clamp kit developed for BMMCC SmallRig 1773 Cage with Ugreen angle HDMI adapter.
      BMMCC HDMI port is rather shaky, especially when used with angle HDMI adapters, so i decide to develop a clamp to solve this problem. After few DIY prototypes i was able to produce small batch of factory machined angle HDMI clamps.
      The package include:
      - Front and rear parts of angle HDMI clamp (factory machined from aluminum alloy, anodized in black color). 
      - 2pcs 1/4" button head screws (Stainless Steel or Black Oxide Steel or both for your choose)
      - 2pcs M4 Stainless Steel grub screws.
      - 2mm allen wrench hex key.
      This clamp designed to work with SmallRig 1773 Cage and Ugreen angle HDMI adapter only.
      You need to get HDMI adapter separately from Ugreen ebay store:
      Or from their AliExpress store:
      Or just look for it in your local electronics store.
      Package price $25 + $5 worldwide shipping and 3% funds transfer fees.
      Currently I can accept payments only with Payoneer Billing Service because PayPal don't works in my country for receiving funds.
      Here are few links explains how the Payoneer Request a Payment service works:
      As an option if you already have a Payoneer account and use it for a while you can just transfer funds without any fee to my Payoneer account.
      The items you ordered will be shipped out from Ukraine, Odesa city. Tracking number will be provided.
      For more details send me a private message or contact directly to radioproektor (@) gmail.com
      More info about earlier development of this clamp can be found and discussed here http://www.eoshd.com/comments/topic/20153-the-simplest-bmmcc-rig-ever-made/

      Long time lurker (finally decided to register), first time poster. I'm selling two gorgeous anamorphic lenses: The trusty Sankor 16c and the Optivision XW 5000. I'm also selling some FD lenses, zooms, Tokina MD Zoom, filters, clamps, and some other bits and pieces.
      Sankor 16c (with lens caps, pouch and original box) - $250
      2X compression, coveted blue flares, small, light weight.
      Barrel has minor cosmetic scuffs, glass is flawless. It's nice, but I've barely used it in the 8 years I've owned it. And you can't go too wide with it. Here's a video I shot with the Sankor/GH13/Helios 44M:

      Optivision XW 5000 - $350
      2X compression, very sharp, large barrel (I can go as as wide as 28mm on the GH13, in 2.40:1. Any wider and you get vignetting. 35mm on the GH13 covers the full frame with no vignetting), lens flare seems to match the color of the light (tungsten looks white, sunlight looks orange, mag flashlights give blue flare).
      The barrel also has minor cosmetic scuffs, but the glass is great. I bought it second hand from a camera shop, so it didn't have lens caps. I do have a small bag I bought for it that I'll throw in for free. Videos shot with the Optivision:

      Vid Atlantic Clamps - $30 each
      Basic Clamp with 60mm thread base, plus 52, 55 and 58mm step rings (the 55 doesn't actually come with the package, but I used one I already had that I'll unclude), extra screws and a pouch for the rings and screws.
      72mm Front Filter clamp, for larger anamorphic lenses/filters.
      '' target='_blank'>>
      '' target='_blank'>>
      Vivitar 67mm Macros (1, 2, 3) - $10 each
      Very sharp, clean glass. I also have a pouch, and 72-67 and 67-72 step rings for use with the filter clamp, macros and macros with filters, included for free.
      Video (Macros with Optivision):
      (The Anamorphic Selfies and Butter videos I posted above used these macro/anamorphic combinations).

      Manfrotto Lens support - $40
      Telephoto lens support that I used to support my Optivision lens as it's bulky and heavy. It has an articulted head, extendable support and a quick release plate, multiple threads for use with a tripod. Very handy, but if I'm selling my Optivision, I won't have any use for it.
      '' target='_blank'>>
      72mm Filters:  Vivitar Variable ND $15, Tiffen Circular Polarizer $15, Tiffen UV Haze 1 Protector $5, Tiffen 4 Filter pouch $5
      Clean, good quaity. I'll include Bower 52-72 and 55-72 step rings and the pouch for free if you buy all three filters.

      Panasonic Lumix G Vario 14-42mm 3.5-5.6 zoom - $70
      Excellent condition, barely used. I'm the original owner.

      Canon EF/s 18-55mm 3.5-5.6 zoom - $70
      Excellent condition, I'm the second owner but I've barely used it.

      Tokina MD 28-70mm 2.8-4.3 zoom - $25
      Minolta MD mount, excellent condition, great quality, pretty fast at wide angle for a zoom (f/2.8). Includes a pouch. I'll also throw in an MD-MFT adapter if the buyer wants it (free).
      Canon 135mm 3.5 FD lens - $10
      Glass is great, but the serial number was scratched off by an earlier owner. It's missing the front lens cap, but has a Hoya Filter protecting it (the owner before had keept it attached at all times, so he said). It's nice, but a bit too slow of an aperture for my needs.

      '' target='_blank'>>
      Canon 28mm 3.5 FD lens - $10
      Excellent condition, glass is clean. Has a generic lens cap and Hoya Skylight filter (came with it when I bought it). Again, nice, but a little too slow.
      '' target='_blank'>>
      '' target='_blank'>>
      Canon 35mm 3.5 FD lens - $10
      Excellent condition, clean glass, includes the original lens caps. Too slow wide open so I never really use it.

      '' target='_blank'>>
      Kalimar 28-105mm 3.5-4.5 FD lens - $10
      I'll sell all four FD lenses together as a kit for $30, or all the Canon primes as a kit for $25.
      Excellent condition, clean glass. It's a decent lens, but I never use it. Includes original lens caps.

      I'll also sell anamorphic kits with clamps, support, macros, filters, etc. at a discount, which will depend on what lens and extras you want.
      I'll accept paypal or cash. If you're in the LA area we can do an in-person transaction, if you're comfortable with that.
      I really need to get rid of a lot of these lenses I never use. I'll always love anamorphic, but I cant stand the dual-focus system, and the general pain of the anamorphic process. I've debated selling them for a long time, but I'm finally ready to let them go. I'd like to spend the money on more lights, and maybe a follow focus/rails, which I've managed to survive without all this time, but it would still help immensely. Thanks for browsing!
